What is Cloud Storage?


One of a company’s most valuable assets is data. Keeping this data secure is essential, and the primary method that businesses have tried to backup data is portable backup media, such as tape. However, data loss is still a frequent problem that companies have to deal with, along with the associated waste of time, money and potentially permanently lost information. As bandwidth and capacity optimisation technology improves, more and more companies are favouring Cloud storage as a valuable alternative to portable media. This article will help you answer the question once and for all - what is cloud storage?

Cloud backup involves sending a copy of the data through a network to an off-site server. The customer pays a fee to the host of the server, usually a third-party service provider, the sum of which is based on capacity, bandwidth or number of users. Subscriptions usually run on either a monthly or yearly basis. These systems are generally built around a client software application that works off a schedule based on the level of service bought by the user.

There are two main methods of Cloud data backup: Software-as-a-Service (Saas) and Hybrid. Backup SaaS is a web-based application accessed via a browser and operated at a central location. It exists as an alternative to the model of on-premise software and secondary service. It is usually built with multi-tenant architecture and a utility pricing model. A pure cloud system copies data directly to the service provider’s cloud. A Hybrid service, on the other hand, copies data with installed storage that resides between your infrastructure and the cloud. This solution comprises on- and off-premise components.

Benefits of Cloud Storage

A Cloud solution works off your current infrastructure, so there’s no need to buy or install any new expensive equipment. The software integrates with your IT system to locate and prioritise files for backup, and then securely transmits encrypted copies to offsite data centres. This is overall a more cost-effective solution compared to buying and maintaining a tape backup system.

Cloud-based backup saves time as well as money. Files can be backed up the Cloud automatically and continuously with an Internet connection. A web-based system makes files easy to find and restore, also saving time.

Backing your data up is pointless if you don’t have a fast reliable restoration protocol in case the unthinkable happens and a disaster causes you to lose data. A cloud backup solution can instantly restore data wherever you are, including individual files.

A Cloud-based system encrypts files to be backed up for transmission, and are encrypted until they reach their destination. The only decryption key is kept by the user. This is much more secure than an unencrypted on-data backup and recovery system.
Storing data in the cloud means that users can access their data anywhere, at any time, wherever there is an Internet connection.

A Hybrid system offers the best of both worlds, as it circumvents the limitations of either an on-premise or a purely Cloud-based solution. The hybrid cloud device offers the advantage of retaining data locally to smooth out transport to the cloud and in case restores are required. It eliminates the need for a complete second data centre or other off-site repository. If you only have one data centre, you can take your back-up data and add it to the Cloud. This data can be retrieved at any time, but with the additional advantage of being able to restore it to a different site.
